Euphorbia
Euphorbia oblongota
Description
Hands down, one of the most versatile and productive early-season foliage plants you can grow. Its bright chartreuse-green umbels combine with nearly every color palette and are perfect for mixed bouquets. Easily mistaken for bupleurum, but has a much longer flowering window and lasts forever in the vase. A must-grow!
Please note: When cut, euphorbia emits a toxic sap that is irritating to the skin and eyes. Use caution and wear gloves when harvesting.
Euphorbia is considered invasive in some areas. If you’re unsure whether or not it’s invasive where you live, a simple web search will help you find the information you need.

Harvesting/Vase Life
Harvest when flowers are fully colored but not completely open. Use caution and wear gloves when harvesting, as the sap is irritating to the skin and eyes. Immediately after harvest, dip the stem ends into boiling water for 7 to 10 seconds to stop the flow of milky sap. Expect a vase life of 7 to 10 days.
