Gloriosa Daisy: Indoor or Direct Sow
How to Sow and Plant
Sowing Seed Indoors:
- Sow indoors about 10 weeks before the last frost
- Sow 1/8 inch deep in seed-starting formula.
- Keep the soil moist at 70-75 degrees F
- Seedlings emerge in about 21 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.
Transplanting in the Garden:
- Select a warm location in full sun with well-drained soil. Plants tolerate a range of soils and can withstand dry conditions.
- 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 18 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.
Sowing Directly in the Garden:
- In mild climates seed may be direct sown any time of the year. Direct sow in a warm, sunny location with well-drained soil.
- Remove weeds and work organic matter into the top 6-8 inches of soil; then level and smooth.
- Sow seeds evenly and thinly and cover with 1/8 inch of fine soil.
- Keep moist.
- Seedlings will emerge in about 21 days depending on soil and weather conditions.
- Thin to stand about 18 inches apart when large enough to handle.
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. Gloriosa daisy is drought tolerant once established.
- 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.

Boy did I get it! These flowers are huge and gorgeous! They bloomed ALL summer long and are still blooming now in the middle of October! I grew two seperate patches of them one with ammened soil (Compost and peat moss added) the other one with out. The patch with the ammended soil far out weighed the other patch so make sure you have decent soil (Virginia Beach has a horrible mix of both clay and sand) and you should have a lovely bunch of daisies all summer long too. I very highly recommend these and I will be growing them again. Great flower, sturdy plant!Date published: 2010-10-19Rated 5 out of 5 by Twigs from Easy to Grow I started these from seed indoors in February and they are blooming abundantly in June. They are not as full (double) as the picture shown, but the flowers are big and eyecatching. I matched them up with red knockout roses and Russian Sage and it is a color great combination.Date published: 2009-07-06Rated 5 out of 5 by LynnS from Great! I grew these from seed years ago and I still get them coming back every year. They are a biannual, but they will reseed themselves. Very hardy and bloom most of the summer into fall. The stems are very study and they make a great cut flower. They are absolutely beautiful!Date published: 2009-01-30
- Many gardeners do not cut back perennial flower seed heads in the fall, but wait until early spring before the new foliage appears. This provides food for wildlife over the winter.
- Divide as needed, as plants can be vigorous.
- Gloriosa daisy is great for beds and borders and as a cut flower.
