Growing: Blood Flower milkweed tolerates light shade, as well as adapting well to either dry or moist soil. In cooler regions it can be grown as a container plant and brought indoors for the winter, or as an annual. These plants are fairly slow to mature. They tolerate some soil dryness, but grow best with occasional watering. Self seeding may occur, but volunteer plants can easily be transplanted or removed while they are still small. Blood Flower attracts numerous butterflies and hummingbirds, and resists deer. Harmless aphids may infest the foliage, but can be removed by a spray of water from the hose. This plant can be cut back at any time of its growth to produce new foliage or tidy its growth. Mature plants can be divided.

All multiple orders of the same seed are put in the same bag. For example if you order 500 beefsteak tomato seeds x 3 then 1500 seeds will be put in the same bag. We do not send out 3 individual bags with 500 in each. This goes for all seeds unless they are listings of different seeds.
