Lisianthus "The Blue Rose"®

Short Description

It's as pretty as a blue rose should be!

Full Description

The 3-3 1/2" rose-like flowers of this amazing plant are a real traffic stopper. The intensity of the flower color softens as the blooms mature, creating a most beautiful display in the garden or vase. The species of this hardy and versatile plant is native to the American Southwest. It is as at home in the garden as it is in containers. Plants grow 18-22" tall and should be grown in a loose, well-drained soil in full sun. Lisianthus tend to be narrow, upright plants and can be spaced 7-10" apart. They look best planted in groups. This annual may act like a perennial in warmer climates.

How to Sow and Plant

Lisianthus may be grown from potted plants

Planting Potted Plants in the Garden:

  • Select a location in full sun with good rich moist organic, well-drained soil.
  • 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.
  • Use the plant tag as a location marker.
  • Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.
  • 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 seeds from germinating.
  • Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of 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.
  • Keep plants well-watered during the growing season, especially during dry spells. Plants need about 1 inch of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
  • 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, as higher rates may encourage root rots.
  • Remove spent flower spikes to encourage flowering and prevent seed development. Pinching the growing tips of plants can encourage bushiness.
  • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
  • Lisianthus is grown primarily for its stunning, long-lasting cut flowers that look like roses.
  • The shorter cultivars are attractive in containers.
  • All types may be used in borders or as edgings, as long as they are spaced closely together.
  • Plants are resistant to heat and humidity.
  • Protect taller varieties from the wind.
  • Pinching can encourage bushier growth.

Lisianthus "The Blue Rose"® is rated 4.6 out of 5 by 12.
Rated 5 out of 5 by from Worth the Money! I had been wanting to try these for years and finally did this summer. They were beautiful plants. I did lose a few. I got the mix of three colors. They really do last a long time on the plant and as cut flowers. They are really beautiful and my twin three year old granddaughters ask for those first when I take them to the garden to cut flowers. I have also seen them at the florist in arrangements and they are gorgeous. I will buy them every year - as plants - I understand they are extremely difficult to grow from seed. But I think I will try seeds anyway at least once. They don't take up a lot of room as the plant itself is not bushy.

Rated 5 out of 5 by from Beautiful Flowers Not really blue, but a deep purple, these are stunning flowers. They stay very well for 5+ days in mixed bouquets. Next year I'll get a mix of colors and keepthe bouquets coming.

Rated 5 out of 5 by from Summer Bloomer for English Cottage Style Garden I have an English Cottage style garden and these are a perfect addition. They are beautiful! Most of the flowers I grow bloom in the Spring so these are great to have blooming in the summer time. The weather here has been very hot (90 - 100 degrees) and these flowers don't mind at all (you have to water of course but they don't wilt at all from the heat). I also planted the Pink Bouquet Collection and they worked just as well.

Rated 5 out of 5 by from Great Success! I was a little worried by some who said these didn't perform. They arrived in perfect shape and bloomed prolifically starting in Late June-July. Used them in bouquets for an August wedding. Very satisfied.

Rated 5 out of 5 by from Growing well My wife loves "blue" so I picked these up and we have them growing in a pot on our patio. First bloom this morning (July 5th) but I planted later than I probably should have. Product arrived in great shape.

Rated 5 out of 5 by from LISIANTHUS I used to buy them as cut flowers in the supermarket and was delighted to find plants a few years ago. I have the purple and white varieties and I overwinter them in the house. I cut them back in the fall. They don't do much all winter, look rather peaked but hello, when the weather gets hot they spring right back and grow like crazy. Obviously I have them in pots and they like it hot and thrive when other plants burn up. I water them everyday, twice a day when temperatures reach the 90ties. Yes they tend to flop but I stake them so they trail. This year I decided to buy some more and will mix them with sweet potato vine, should be beautiful. I also found a few seedlings sprouting up in pots 20 feet away, which makes me believe that they are easy to grow from seed.

Rated 4 out of 5 by from Beautiful BUT..... They are not BLUE. They are purple. I bought these for my daughter's upcoming wedding. Her colors are blue and white. She wanted blue roses VERY expensive. We found these and thought close enough and we thought it would be a fun project for us. I have pampered these plants. They are beautiful flowers, I have staked and loosely tied them to keep them from flopping over. I have a stunning display of PURPLE rose lisianthus. Too bad they are not blue.

Rated 5 out of 5 by from Growing recommendation I have grown these in the past, so I prepared for a large display this year. Knowing that this variety will flop over, I cut a section of fence wire with 2"x4" holes in it and bent it over so that both long sides were touching the ground and the hump in the center was 6-8" above the ground. They have easily grown through the wire and that stay nice and upright even through high wind. I planted them about 6" apart and the display is beautiful. I arrange alot of flowers and love these as they are long lasting. If length is desired, you can insert it in a flower tube. They are easy to grow, but if they decide to shrivel up, these is nothing you can do to save them, so don't let them dry out! Am entering one stem in the flower show today, and if I win, I'll pass on an image!
