  • Lobelia: Indoor Sow or Potted Perennial Plant

    How to Sow and Plant

    Sowing Seed Indoors:

    • Sow indoors seeds 8-12 weeks before the last frost
    • Sow thinly and just press into seed-starting formula
    • Keep the soil moist at 65-75 degrees F
    • Seedlings emerge in about 20 days
    • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
    • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
    • If you are growing in small cells, you may need to transplant the seedlings to 3 or 4 inch pots when seedlings have at least 2 pairs of true leaves before transplanting to the garden so they have enough room to develop strong roots
    • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning.  This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

    Planting in the Garden:

    • Select a location with well-drained, rich, moist soil in partial shade to full sun. If in full sun, make sure plants get plenty of water.
    • Prepare the bed by turning the soil under to a depth of 6-12 inches removing any debris, and lightly raking as level as possible.
    • The addition of organic matter (leaf mold, compost, well-rotted manure) benefits all gardens and is essential in recently constructed neighborhoods.
    • Plant on a cloudy day or in late afternoon to reduce transplant shock.
    • Dig a hole for each plant, approximately 6-8 inches apart large enough to amply accommodate the root ball.
    • Unpot the plant and gently loosen the root ball with your hands to encourage good root growth.
    • Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.
    • Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.

    How to Grow

    • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination.
    • Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time.  Always keep mulches off a plant’s stems to prevent possible rot.
    • Careful watering is essential in getting perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry.  One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.
    • Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary.  Good air movement is also important.
    • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Garden-tone, as higher rates may encourage root rots.
    • Deadhead to encourage repeat blooming.
    • Pinch plants if you prefer bushier growth.
    • Do not cut back in fall, cut back in spring.
    • Divide every 2-3 years.

    Growing Tips

    • Perennial lobelias are useful for difficult wet locations. They are attractive in the middle or back of the border, and naturalize well in woodlands and along stream banks. They are very effective massed in the landscape.
    • Lobelias make great cutting flowers as well. Cut when flowers are 1/3 open.

  • Lobelia, Cardinal Flower is rated 3.875 out of 5 by 8.
    Rated 5 out of 5 by from So glad I bought these! I bought 3 of these plants in Spring 2015 and planted them right away. They steadily grew until they were over 3ft tall (in partial shade) and oh my gosh they are so pretty in bloom! This must be the prettiest, purest shade of red I've ever seen. And yes they do attract hummingbirds! This is such a perfect plant that I can't believe more people don't grow them. I love my Cardinal Flowers!

    Rated 5 out of 5 by from Really worked out well I took delivery of four Cardinal Flower plants from Burpee on March 23, 2012. I immediately watered them while they were in they were still in their shipping pots then let them acclimate to their new surroundings for three days before planting in the garden. They showed no signs of life for a few weeks before taking off like rockets. Four months (July 31) after planting my tallest one just topped five feet. Another is at four feet and the third is around 42 inches tall. The fourth one was lost in a gardening accident. All three surviving plants are producing spectacular flowers that are drawing hummingbirds as July turns to August. The soil they are growing in is loam that has been well cared for over the years. I mulch it with cedar in the summer and in the fall all the leaves from my yard go into the bed. My house is in the city not the country. These plants exceeded my expectations and I plan on purchasing more.

    Rated 5 out of 5 by from Amazing growth! I got my lobelia in the Fall (October), planted it right away, and prepared it for the winter. It was minuscule on the ground and appeared so frail that I was afraid it was not going to make it. Spring came and the other plants started coming out of their dormant states, but my little lobelia was still there looking sad and dry, but not quite dead. I started worrying anyway. A few weeks passed and one day I noticed one bright green-looking growth. Then I completely redid my border, a work in progress: changed the topsoil and by the same token moved the lobelia to a sunnier location. Soon another growth came, and since, it's been growing like a weed! It has 3 abundantly leafed growths now, the tallest measuring about 2 feet. It's by far my most successful plant. On sunny days, in the mid-afternoon, it starts leaning and leaning... it gets dehydrated quite fast!! A good watering and it peaks right back up. Watering twice a day is a must, it seems. It may well have thrived because of all of the rain we've been having. So, lots of beautiful green so far, and I'm hopeful I may get to see some red later in the year. But maybe not, and that's okay, I'll be patient and wait till next year.

    Rated 3 out of 5 by from May not know for a while Mine is also just sitting there doing nothing. I did a little research. Apparently the first year this flower will simply be a small rosette-like plant, similar to what I received. According to one writer it will flower in year two. It's still too early to tell if the plant Burpee sent was a first or second year plant. It's been a few weeks and there hasn't been any new growth yet, though I expect little until late May or early June.

    Rated 2 out of 5 by from Mine Won't Grow Either I'm having the same problem as Tiggerific. I bought six of these plants and, though they're all alive two months later, they haven't grown at all. They're alive, but act like they're dormant. Is this supposed to happen? Could the problem be too much or too little sun or water?

    Rated 1 out of 5 by from Dud Unlike the Coreopsis that also came with this order, this plant arrived rather lifeless. I planted it immediately, but it's shown no signs of life...while the Coreopsis has already tripled in size.

    Rated 5 out of 5 by from An Absolute Delight This species of cardinal flower--a plant that my dad introduced to me--is perhaps the favorite perennial in our garden. The plant arrived extremely healthy and had no problems adjusting to its new home; in a week or two it looked like a lifelong native. The tall stalks' many flowers are a rich, vibrant red, and the blooms linger for a good while, allowing you to enjoy them for a gratifyingly long time. There is a down side, of course: you may have to wait in line behind the hummingbirds that will become regular or perhaps more frequent visitors to your garden. This is a treasure that you will look forward to seeing each and every year.
