As one of the whitest poinsettias on the market, Alpina provides early-season color ideal for week 47 sales. Plus, the medium vigor works well in many pot sizes.

Plant Vigor: Medium
V-Shaped Habit: Normal
Response Time in Weeks:
  • Season:Early Season
  • Foliage:medium green
  • Natural Flower (first pollen):Nov. 16-20
  • Response Time in weeks (first pollen):7.5
  • Vigor:medium
  • Habit:normal
  • Average Bract Size:large, pointed
  • Post Harvest:good
  • Energy Efficient:
  • Varieties are rated from most () to least () efficient. Contact us for guides.

  • Cool Finish (24 hrs avg.):63°F / 17°C
  • Indicates minimum temperature starting two weeks after the beginning of short days. Please note that a crop grown cooler requires more time to finish (4 to 7 days), and will have smaller bracts and darker color (for example, white may turn cream-yellow). Toward the end of the crop (two weeks prior to shipping), slowly lower the temperature for green-leafed varieties to 65°F (18°C) day/night and dark green-leafed varieties to 63°F (17°C) day/night.

  • Space Efficient:
  • Varieties are rated from most () to least () efficient. Contact us for guides.

  • Recommended spacing for 6":13"x13"
  • 2.5" Mini
  • 4 - 5"
  • 6"
  • 8"
  • 10"

“Alpina is an early-season, true white variety. To maintain brightness of the white color, avoid keeping cool for long periods.”



  • Roots rapidly; plant from liner at 22-24 days.
  • Apply rooting hormone to the base of cutting.
  • Start feed program around day 7.
  • More moderate vigor level than some others; may not require PGR application in propagation.
  • Important to plant from liners into finished container as soon as they are well rooted.
  • Branches aggressively, very early and will branch based on leaf maturity, not just pinch.
  • Failure to feed early enough will result in yellowing and hardening of liner; some early feeding in propagation is recommended.

early finished growth

  • Strong-branched variety must be pinched early: at day 12-14 from a liner; at day 22-24 for direct stick.
  • Failure to pinch early will result in uneven branching; important to pinch leaving only as many leaves as you need branches; will produce a branch at every node.
  • Apply light PGR when branches are 1-1.5 in. (2.5-4 cm) using Cycocel spray at 500 ppm or 750 ppm; recommended to even out the branches.

growing on

  • Grows steadily once the branches develop and exhibits consistent moderate growth throughout the crop until color begins.
  • Northern Climate: PGR should be limited to only Cycocel spray at 500 ppm.
  • Southern Climate: Can use Cycocel spray up to 1,000 ppm. Use 1-2 spray applications of B-Nine (1,000 ppm)/Cycocel (500 ppm) before September 20.
  • Avoid late applications of PGR as they can affect the whiteness and size of the bract.

late growing stages

  • Strong root system; requires continuous feed until finish.
  • Watch media EC; reduce feed levels to avoid rapid increase in media EC as this indicates the plants need for nutrition is waning.
  • High EC at finish can result in root damage, reduced shelf life and possible Pythium.
  • Can be held cool but will reduce whiteness; pay attention to the humidity and avoid dew point to prevent Botrytis.
