Standing Cypress is one of the most showy plants in my garden in mid July. We have learned a very interesting thing about this plant, when it is growing upward and before it sets it's flower, cut the plant down by half it's height. It will sprout several new tops and each stalk will bloom as profusely as the single stock would have, thus multiplying the magnificence of this flower. You will greatly increase the amount of blossom, the plant will not attain as much height, but the added blossom makes up for it. I leave some of the plants closer to the center of the bed alone where more height is desired.

Best planted in back of a lower-growing plant or the tall spires will flop; cannot be staked. Seeds will sprout anywhere, including in cement cracks. Does not like to be transplanted. Very feathery and delicate when in full bloom. Grows to 3 feet tall; does not spread except by seed. Reseeds freely if stems are allowed to dry on the ground.

An excellent hummingbird flower. Standing cypress is a biennial that will often bloom the first year. It should be directly seeded into the garden to perform it’s best. The tall spikes can get up to 6 feet and have bright tubular flowers. It likes full sun and a well-drained soil
