      Yuccas are a striking addition to gardens, with bases of long spiky leaves and tall spires of flowers. Common in deserts, they come as both shrubs and trees. They grow well in full sun with well drained soil of any variety. There are many hardy varieties that can also tolerate a range of temperatures, with their white flowers generally appearing in mid to late summer. Be careful about where you position yuccas; their leaves are surprisingly sharp and can cut people who walk past.

      Recommended Temperature: 0°C-35°C (some frost-tender varieties should be brought inside in the winter.

      Watering: About once every ten days; water less in the winter.

      Toxicity: Toxic to dogs and cats, generally causing mild vomiting and diarrhoea.

    • Vinca

      Vincas (also known as periwinkles) are evergreen groundcover shrubs that bloom with pretty five-lobed flowers. They're very flexible plants and can be grown both in shade and light shade, making them perfect for beautifying areas darkened by trees. Vincas aren't too fussy about soil either and will happily grow in both acidic and alkaline varieties. However, the downside is that they spread like wildfire and can be pretty invasive; so they shouldn't be planted in smaller gardens or in borders near other plants. You can tackle their tendency to spread by uprooting new runners as they appear.

      Recommended Temperatures: 15-20°C
      Watering: Weekly if flowering; twice per week if not.
      Toxicity: Mildly to moderately toxic, causing loss of coordination, seizures, diarrhoea, vomiting and depression.

      Tulips produce beautiful blooms in a huge range of colours, perfect for creating that colour-coordinated garden and brightening up your space in the springtime. The most common colours are red, white and yellow. They are famed for their popularity and prominence in the Netherlands - in fact, the tulip craze there hit the point where a handful of bulbs cost more than a townhouse in Amsterdam! Tulips like plenty of sunlight, but aren't keen on excessive amounts of moisture - good drainage is a must for growing these beauties.

      Recommended Temperatures: 0-13°C: tulips require a cold period of around 12-14 weeks to develop.
      Watering: Every 7-14 days (rain will usually do the job for you)
      Toxicity: Toxic to dogs and cats. Highest levels of toxins are found in the bulb; ingestion can cause vomiting, diarrhoea, depression and hypersalivation.

      Save yourself a trip to the shops and grow your own tomatoes instead! There are lots of different types to grow, from succulent cherry tomatoes to versatile salad tomatoes and plump beefsteak varieties. No0 matter which you choose, they love the heat, so plant them somewhere warm and sunny in late spring or summer. Taller varieties require stakes or trellises, but there are also bushy species that can be grown independently.

      Recommended Temperatures: 18-30°C
      Watering: Daily (little and often is the rule of thumb)
      Toxicity: Tomato leaves, stems and unripe tomatoes are toxic to dogs and cats.

      Thyme is an aromatic evergreen herb with a slightly minty flavour that tastes great in stews, soups and plenty of other dishes. Thyme originates from the Mediterranean and so prefers a spot with full sun and well-drained soil. They're drought-tolerant and can rot if the soil stays too wet; this is a particular risk during the winter. Thyme is hardy and can be harvested throughout the year - so if you're a fan of thyme, you'll never go without!

      Recommended Temperatures: 15-21°C (however, it's hardy and able to tolerate temperatures below freezing)
      Watering: Every 7-14 days - avoid overwatering.
      Toxicity: Non-toxic

    • Strawberry

      Love strawberries? Then you'll be pleased to know they're both very easy to grow and incredibly versatile. You can plant them virtually anywhere in your garden, including borders, pots and hanging baskets, as long as there's plenty of sunlight, fertile soil, and enough shelter to keep them protected. Another benefit is that you don't have to wait long for strawberries to start bearing fruit; they'll produce their first crop in just 60 days.

      Recommended Temperatures: 15-26°C
      Watering: Daily when plants are getting established. Once the plant is fruiting, make sure it's dried out before watering again - too much water can cause the fruit to rot. Similarly, water from below to avoid oversoaking the plant and fruit.
      Toxicity: Non-toxic
