Q

Plant Families (end in -aceae): what they’re useful for.

A

-Useful for knowing similarities between plants, think of plants in a family as cousins (ex. squash)

16
Q

natural variation in a species

A

variety (ex. var. contorta)

17
Q

human-selected and vegetatively propagated and maintained variety

A

cultiva

18
Q

difference in a species too subtle to be a variety

A

forma (ex. f. glauca)

19
Q

cultivar that is sexually propagated

A

Line (ex. genus cross: Rosa x hybrida & species cross: X Fatshedera (Fastsia japonica x Hedero helix))

20
Q

group of similar lines (often just a different flower color)

A

series

21
Q

cross between two species or general

A

hybrid (

22
Q

Classification by overwintering adaptation (name the two categories)

A
  • Herbaceous (succulent): soft annual tissues, survive winter below-ground (if at all)
  • Woody: hard perennial tissues - survive winter above-ground
23
Q

Classification by growth habit (name the two categories)

A
  • Vines: herbaceous plants that climb or twine up vertical supports
  • Lianas: vines that develop woody stems over time
24
Q

Classification by growth habit and size (name the three categories)

A
  • Herbs: herbaceous self-supporting
  • Shrubs: woody self-supporting (smaller)
  • Trees: woody self-supporting (big)
25
Q

Classification by tolerance to frost or freezing (name the two categories)

A
  • Tender: readily damaged by frost
  • Hardy: not easily damaged by frost, flower buds usually less hardy than leaf buds, roots may also have diff freeze tolerance
26
Q

By preferred growing temperatures (name the two categories)

A
  • Warm Season: like warm temps (squash, lima beans, sweet potatoes, etc.)
  • Cool Season: like cool temperatures (broccoli, kale, lettuce, etc.)
27
Q

Classification by water requirements/preferences (name the four categories)

A
  • Hydrophytes: grow in water or in continuously wet soils
  • Mesophytes: grow in soils that range from wet to dry many times during the year (most horticultural plants)
  • Xerophytes: adapted to seasonal or persistent drought (cacti, some succulents)
  • Halophytes: adapted to growing with high salt concentrations (beets, spinach, salt-bush)
28
Q

Classification by soil pH preference (name the two categories)

A
  • Acidophiles (blueberries, rhododendrons, azaleas)

- Basophiles (coltsfoot)

29
Q

Classification by growth pattern/longevity (name the four categories)

A
  • Annuals: seed to seed in one season, then DIES
  • Winter Annuals: germinate from seed in fall and overwinter before producing seed the next spring and DIE
  • Biennials: seed to rosette in 1 season; rosette to seed spike in 2nd season then DIES
  • Perennials: may take several years to reach reproductive maturity; will reproduce seeds annual (under favorable conditions) for multiple years without DYING
