Deep red flowers, beautiful long lasting blooms. Mine generally reach about 7" - 9" across. I find mine do best when planted in containers (instead of directly in garden) in full sun with rich, loose, well drained soil. Give a spritz of liquid fertilizer once ever couple of weeks. Plant the bulbs at about 6" depth.

Absolutely beautiful, dependable dahlia that I've grown for the last 3 years. Since I'm in zone 5, I set the bulbs out in May (usually mid month). If frost is possible, cover tender vegetation on those nights with a cardboard box or remay cloth. Blooms generally appear by the end of June/ early July and continue until frost. When frost arrives, lift bulbs, cut off plant close to top of bulb, clean off with water and put in airy place to dry. I store mine in my basement over winter in net bags hanging up. Or put in box with a little peat moss or wood chips and store in cool dark place (45 - 55 degrees).

Because this is a dinnerplate dahlia, if the blooms reach 8+ inches across, you can dry these for use in dried arrangements and they will form a nice fist sized dried flower when fully dried. (smaller blooms dry much smaller). Color will hold for about 1 year.

To dry: cut (just) fully opened flower and leave a short (4" stem). Poke a 22 ga or 18 ga wire through the flower close to but not in the center of the flower. Loop the top wire into a U and pull down through the opposite side of the flower. Hang upside down in a warm dark place to dry (about 3 weeks). When dry, spray well with a flower preservative or hair spray to seal. I have read that you can preserve the blossoms using silica gel as well, but if you intend to do more than 1 or 2 flowers, air drying is best. Flowers dried in silica gel will absorb moisture from the air and fall apart much quicker.
