EUPHORBIA cyparissias
Plant Description
| Life Cycle: | Perennial |
| Family: | Euphorbiaceae |
| Origin: | Europe, Turkey |
| Special Features: | Suitable for naturalizing in thin light soils. Beautiful chartreuse flowers. Give the durable, cypress spurge plenty of room to grow. Spreads by rampant underground runners. Has the intention to overgrowth. Drought tolerant species. Avoid contact with the milky sap of the leaves that can cause dermatitis. |

| Sowing Direction: |
(1) Cold-germinators are still referred to as frost-germinators, although this isn’t quite correct. The sowing must be kept warm (about +18 to +22°C) [about 64 to 72°F] and moist for the first 2–4 weeks. After this period the sowing must be kept at a cold temperature (between –4 and +4°C) [between 25 and 39°F] for another 4–6 weeks. Colder temperatures of –5°C [23°F] are only advantageous for most species of the Ranunculus family. It is not so important if the temperature is higher or lower during the cooling period, but the cooling period has to be prolonged because the synthesis of the germination inducer, hormon-like acid, slows down or comes to a standstill.
|
| Best Sowing Date (northern Hemisphere, Field condition): |
late autumn - early spring |
| Sowing to Germination: | 8 - 10 weeks |
| Germination to Transplant: | 4 - 8 weeks |
| Transplanting to Potting: | 8 - 10 weeks |
| Cutting back at Transplanting: | Not Necessary. |
| Container Size(s): | 1 plug per 8/9 cm (3 1/2") / 1-2 plugs per 11/12 cm (4 1/2") / 2-3 plugs per 15 cm (6") |
| Vernalization: | A prudent recommendation would be to provide 6-12 weeks at an average daily temperature of 40°F (5°C). Exposure to cold may not be necessary for flowering but might improve quality. |
| Forcing: | This species is not a suitable candidate for forcing. |
| Fertilizer: | Light (100-150 ppm) |
