Bold & Hardy Summer Blooms Collection
Wake up the summer doldrums with our Bold And Hardy Collection of spring planted, summer-blooming bulbs. These hardy bloomers will add delightful texture, color, and form to a sunny space or perennial garden. Not fussy, they are low-care perennials that are deer resistant, pollinator favorites. Foxtail Lily (Eremurus stenophyllus) flowers from June through July at a compact height of 2-3' making it a perfect companion to the deep scarlet blooms of Lucifer Crocosmia (Montbretia). Casa Blanca Lilies (Lilium) blooms in mid-summer with pure white, fragrant flowers. Plant ‘Casa Blanca’ amongst other perennials where it can grow with its feet in the shade and extend up into the sun where its big, perfumed flowers can shine. All of these beauties make lovely cut flowers too. Three varieties, 16 bulbs total.

Soil Preparation: Remember that proper soil preparation is the key to healthy, vigorous blooming perennials. Use Yum Yum Mix and a high quality compost at recommended rates to prepare the soil. Inoculate the plant roots with Plant Success mycorrhizal inoculant. Planting: Plant according to the mature size of the plant. Don’t be tempted to put the plants too close based on their size in the pots. They’ll grow quickly and cover the space shown in the planting map. (Maps included only with Pre-Planned Gardens, not Collections.)
Fertilizing: Once annually in mid-fall, after plants begin to go dormant. Use Yum Yum Mix or Yum Yum Mix Winterizer at recommended rates to improve the soil and provide essential plant nutrients.Use it with high quality compost, mix half and half by volume and spread on top of the soil. Scratch it in lightly and water thoroughly. It is also beneficial to treat the plant roots with Plant Success® mycorrhizal root inoculant if you didn’t do so at planting time. (Inoculation only needs to be done once.)
Mulching: In arid climates mulching is very beneficial. Coarse textured composts, shredded leaves, pine needles and composted bark are all excellent mulch materials. Apply to a depth of 1-2 inches. Replenish annually (or as needed).
Summer Blooming Bulbs, including popular varieties such as gladiolus and dahlias, are planted in the spring and bloom in the summer. Most of these bulbs are tropical and require warm weather to be planted. There must not be any danger of frost and your ground temperature must have reached 55 degrees Fahrenheit before planting. Many of our summer blooming bulbs can be planted as perennials in zones 9-10 (zone 8 if mulched), but should be treated as annuals in cooler climates. You can lift them and store them in the fall, or bring patio pots inside before frost. See page 15 of our Planting Guide for a bulb depth planting illustration.

Q & A
Suggested Companion Plants:
USDA Hardiness Planting Zones
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
- If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
- If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
