Across
  1. 5. Plants that retain their foliage throughout the year
  2. 7. A plant cultivar resulting from the intentional cross-pollination of two closely related species or varieties
  3. 8. Plants that spread aggressively and are difficult to eradicate
  4. 11. Essential nutrient responsible for green vegetative growth in plants
  5. 12. Intermediate soil particle, .002 to .05 millimeters; silt combines the best traits of both sand and clay particles, retaining moisture and nutrients effectively while draining freely
  6. 13. what an annual plant does when it sends up a flower stalk and sets seed; the term is typically applied to cool season vegetable crops that go to seed prematurely as a result of hot weather.
  7. 16. these are plants that do not tolerate freezing weather and must be brought indoors in order to survive the winter; examples include heliotrope, fuchsia and begonia
  8. 17. A common ingredient in potting soil, a mica-like mineral that has been heated, causing it to expand into a spongy material with exceptional water and air holding capacity
  9. 19. Material used to protect the soil, including wood chips, straw and bark nuggets; protects the soil from erosion, adds organic matter, conserves moisture and keeps plant roots cool
  10. 20. Plants that lose their foliage during the winter months
Down
  1. 1. A plant that lives year after year; all woody trees, shrubs, and vines, and many herbaceous species
  2. 2. A plant variety developed through selective breeding; and are developed for many purposes, including fruiting, flowering, and disease-resistance characteristics
  3. 3. The tiniest particles found in soil, less than .002 millimeters in size; it excels at holding both nutrients and moisture, though they drain poorly and become rock-hard when dry
  4. 4. The largest particles found in soil, .05 to 2 millimeters in size; soil with a high sand content drains readily, but nutrients are easily leached away
  5. 6. Plants with multi-colored foliage
  6. 7. Plants that do not have woody stems, only soft green stalks, and leaves
  7. 9. A plant that lives for only a single growing season; most grow in spring and summer, dying with the first frost of fall, though some species thrive in cool weather, setting seed and dying when the weather warms in spring.
  8. 10. Loosening the soil to introduce more air and improve drainage
  9. 14. Fertile, well-drained soil; having an ideal balance of sand, silt, and clay particles, along with abundant organic matter and humus content
  10. 15. In the taxonomic classification of organisms, this is the rank above species and below family (plural: genera); it is synonymous with the “scientific” or “Latin” name of plants (i.e. Rosa, Salvia and Quercus) and is always capitalized
  11. 18. A common ingredient in potting soil, perlite is a volcanic mineral that has been heated, causing it to puff up; has exceptional water and air holding capacity, which helps to prevent soil from becoming compacted or drying out
