Provide two types of plots that you have visited in HortPark and describe the special features based on two plots.

I'm sorry, but as an AI, I don't have personal experiences or visit places. However, I can provide information based on available data.

1. Butterfly Garden: This is a popular plot in HortPark. It is specially designed to attract butterflies by planting specific types of plants and flowers that butterflies are known to be attracted to. The garden is filled with a variety of colorful flowers and lush greenery, providing a perfect habitat for butterflies. Visitors can enjoy the sight of various species of butterflies fluttering around and even landing on them. It's a great place for photography and learning about different butterfly species.

2. Silver Garden: This plot features a collection of silver, grey, and white hued plants, creating a unique and visually striking landscape. The plants chosen for this garden are known for their resilience in harsh, dry conditions. The Silver Garden is not only beautiful to look at, but it also serves as a demonstration of how diverse and adaptable plant life can be. It's a great place for those interested in botany or gardening to learn about these unique plants.
